Yes.

Lambert's law is a cosine function describing reflected light intensity. In practical terms it means you see maximum light intensity when you look head on at something, but the intensity drops off as you move to one side or the other. A graph of the rate at which it drops off mimics the cosine graph.

What is the illumination of a surface by a light source directly proportional?

The illumination of a surface by a light source is directly proportional to the intensity of the light source and inversely proportional to the square of the distance between the light source and the surface. This relationship is described by the inverse square law of illumination.


How does the illumination on a surface vary with distance from a light source?

The illumination on a surface decreases as the distance from the light source increases. This is because light spreads out as it travels, leading to a decrease in light intensity the further away from the source. The relationship between illumination and distance follows an inverse square law, where doubling the distance results in a fourfold decrease in illumination.


Is entropy closely related to the 1st law of thermodynamics?

Entropy is closely related to the 2nd law of thermodynamics, not the 1st law. The 1st law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. Entropy, on the other hand, is a measure of the disorder or randomness of a system, which increases over time according to the 2nd law of thermodynamics.


How are boyle's law and charls's law related?

Boyle's Law and Charles's Law are both gas laws that describe the behavior of gases under different conditions. Boyle's Law states that pressure and volume are inversely related at constant temperature, while Charles's Law states that volume and temperature are directly related at constant pressure. Together, these laws help to understand how gases behave and the relationship between their properties.


The first law of thermodynamics is related to the conservation of which quantity?

Yes. There are no known exceptions - otherwise it would not be considered a law
